Описание: This unique survey describes the world’s ancient phosphorite deposits on a scale never previously attempted. The International Geological Correlation Programme started Project 156, on world phosphate resources, in 1977. An international team of forty-six researchers describes in twenty-five chapters almost 100 Precambrian or Cambrian deposits of phosphate rock, extending through all continents except Antarctica. The total resources are large, but only a small fraction is minable at present. The data presented give a good understanding of the distribution, nature and origin of phosphate deposits. The book is an important contribution to the scientific understanding of phosphate deposits, as well as a valuable aid to the search for an exploitation of phosphates in many parts of the world.
Описание: Earth surface processes, landforms and sediment deposits are intimately related - involving erosion of rocks, generation of sediment, and transport and deposition of sediment through various Earth surface environments. These processes, and the landforms and deposits that they generate, have a fundamental bearing on engineering, environmental and public safety issues; on recovery of economic resources; and on our understanding of Earth history. This unique textbook brings together the traditional disciplines of sedimentology and geomorphology to explain Earth surface processes, landforms and sediment deposits in a comprehensive and integrated way. It is the ideal resource for a two-semester course in sedimentology, stratigraphy, geomorphology, and Earth surface processes from the intermediate undergraduate to beginning graduate level. The book is also accompanied by a website hosting illustrations and material on field and laboratory methods for measuring, describing and analyzing Earth surface processes, landforms and sediments.
Описание: Extensive descriptions of a wide range of key or world-class mineral deposits of China are presented in the context of the country’s general geology, tectonic units and mineral systems and their geodynamic evolution within the tectonic framework of the Asian continent. This comprehensive overview, incorporating the latest geological concepts, is the first such coverage written in English by a western expert, and will be of benefit to mineral explorers and miners, as well as to research scientists and students in institutions of higher education. In his compilation of this compendium of Chinese geology and mineral systems, Franco Pirajno draws on first-hand knowledge of China’s geology and mineral deposits gained in numerous field visits and research projects with Chinese colleagues from various academic institutions over the past 18 years.First time that a western-based book on China’s geology and mineral deposits is published Appropriate for use by the mineral exploration industry Modern English-language geological and mineral deposits information on China Most useful to Western (and Chinese) geoscientists
Описание: In 2002, the Swedish Metal Information Task Force (MITF) engaged the Environmental Research Group (MFG) to update previous monographs on copper, zinc and major alloying metals (such as chromium, nickel and molybdenum) in society and in the environment. This book presents new results on metal fluxes from society to the environment, on metal speciation in water, soil and sediment, and its interpretation in terms of mobility, biological uptake and toxicity. The scientific fundamentals of new approaches, like the Acid Volatile Sulphide (AVS) concept to predict metal bioavailability in sediments, and the Biotic Ligand Model (BLM) to calculate the toxicity of metals to aquatic organisms, are critically evaluated, with a focus on copper, nickel, zinc, and, in part, chromium.Recent scientific advances now offer an improved understanding of the mechanisms and factors controlling the intricate behaviour of trace metals, their interactions, uptake and effect in natural systems. Traditional risk assessment methods usually built on quite crude toxicity tests done in unrealistic "laboratory waters", and did not consider natural conditions. In contrast, modern approaches now increasingly involve the full utilisation of site-specific factors, which are decisive for the formation of bioavailable and toxic metal forms. Audience: This book provides excellent guidance not only to scientists focusing on the assessment of the ecological risk of metals, but also to authorities, decision makers in industry, educational staff and the interested public concerned with the occurrence and fate of trace metals.

Описание: From an author whose international academic and industrial experience spans some 40 years comes this unique book offering material for comparative research in metallogeny, practical tips for metals explorers, and even inspiration for commodity investors.
Описание: Slope deposits are common in any inclined relief. So-called cover beds may veil entire landscapes, in which case they are commonly overlooked or confused with soil horizons. This book focuses on these widespread deposits and discusses their properties, genesis, and age mainly in subdued mountains of Central Europe, where to date most research on the matter has been conducted. The ecological consequences of such slope deposits on soils, slope water dynamics, and slope failures are addressed. Finally, transfer of the cover-bed concept to other mid-latitude regions is attempted for the reconstruction of landscape evolution. This unique compilation, covering several decades of a facies-oriented approach to slope-deposit research, delivers deep insight into the wide field of research on cover beds and encourages researchers all over the world to take an in-depth look at the critical zone as to its possible stratified nature.

Описание: This volume provides an overview of uranium geology which includes data characteristics for uranium deposits and a synthesis of this data in the form of a
typological classification of uranium deposits. These are supported by more detailed descriptions of selected uranium districts and deposits. The book is separated into five chapters: a
summary of world uranium resources and production; uranium geochemistry; the principal aspects of the genesis of uranium; the principal recognition criteria, dimensions and
metallogenetic aspects of identified types of deposits; and selected uranium districts and deposits.

Описание: This book is the second of four reference volumes which collectively describe the achievements of the International Geological Correlation Programme Project 156 (Phosphorites) during the ten years of the Project’s existence. Volume 2 contains 93 chapters contributed by 111 researchers, dealing with most, if not all, of the major individual deposits or phosphate fields of the world, whether of igneous or sedimentary origin. Total resources of phosphate rock are extremely large, but are unequally distributed geographically and only a relatively small proportion can be mined on an economic scale at present. The text is arranged on a continental basis, with an introductory chapter for each continent summarising the distribution of resources within the geological timescale. This unique volume provides a good understanding of the mode of occurrence, geological setting and phosphogenesis of the world’s phosphate resources. It forms an invaluable aid to the search for, and exploitation of, phosphate deposits in many countries.
